I Specification of Letters Patent.

Patented Mar. 4, 1913.

To all whom it may concern:

Be it known that I, JAMES A. KEYEs, a citizen of the United States, andresident of the city, county, and State of New York, have made certainnew and useful Inventions Relating to Wrapping-Machines, of which thefollowing-is a specification, taken in connection with the accompanyingdrawings, which form a part of the same.

This invention relates to wrap ing machines and relates especially to.mac ines for wrapping cakes of soft or weak material such as compressed.yeast and the like, although. of course, these machines may be used forwrapping other articles.

In the accompanying drawings showing in a somewhat diagrammatic way, anillustrative embodiment of the invention, Figure 1 is a side elevationwith the adjacent frame member removed, Fig. 2 is a similar view fromthe other side of the machine, Fig. 3

is an end view' looking from the left in Fig.

1, Fig.4 is the opposite end elevation, Fig. 5 is an enlarged sectionalview of the paper feed rolls, Figs. 6, 7 and 8 are enlarged detail viewsof the lifter devices, Fig. 9 is a top view showing the folding devices,Fig. 10 is an enlarged vertical. sectional view of the folding plungerand associated devices, Fig. '11 is a horizontal section thereof alongthe lines 111l of Fig. 10, Figs. 12 and 13 are enlarged transverseshowing progressive folding operations,

Figs. 1-1and15 are similar side elevations,

Fig. 16 is a detail view taken at right angles showing this end folder,and Fig. 17 is a perspective view showing the wrapped cake.

In the illustrative embodiment of this invention shown in the drawingsone or more wrappers of paper or the like, may be used to inclose thecake of yeast or other article and they may be in the form of continuouswebs 1, 2, the inner web 2 being of waxed paper or the like if desired,and the outer wrapper strip or web 1 being if desired, printed withsuitable advertising matter and also perforated with alining aperturessuch as 231 indicated in Fig. 5 to regulateits alinement. The innerwrapper 2 may pass over the guide roll- 4 in the bearin brackets '3 andover the similarly a justable guide roll 12 in the bearings lland thenthis inner wrapper may pass over the guide 13 provided if desired, withthe frictional gripping finger 14 indicated in Figs.

- .of the roll to the desired extent.

sectional views i 4 and 5, in order to maintain the proper tension inthe web and prevent its moving backward when released. The outer orprinted wrapper 1 may pass over the similar guide roll 5 in the .bearinbrackets 6 supported on the extensions 7 and then over another guideroll 8 in the adjustable bearings 9 before passing over the feed board16 and into the bite of the feeding and cutting rolls 19, 20, indicatedin Fig. 5.

The knife roll 19 on the shaft 17 65 may be provided with the transverseknife or cutter 25 mounted in suitable yielding material so that itsedge projects from the 'periphery' The 00- operating roll may have arecessed block of wood 26 to cooperate with the knife and may be rotatedby its shaft 18 ill-111115011 with the cutting roll so asto feed thepaper strips between them and severthem at the proper time. In order toallow strips of different length to be used in the machine it isdesirable to form the knife 'roll with a fiat releasing portion orface'23 on its periphery so that when this portion 23 comes intoengagement with the opposing roll the wrapper strips are not gripped butmay be longitudinally adjusted to the desired extent. A suitablefriction retarding device may .be used in connection with the outerwrapper strip and the frictional gripper 32 may be faced with rubber orother material to engage the wrapper with the desired effectiveness.This gripper may be mounted on the rock arm 31 connected by the linkwith the rock lever 29 and the link 28 connected with this rock levermay carry at its lower portion, the cam roll 27, cooperating with thecam 24 on the shaft of thecut-ter roll so that the gripper 32 is nor- 95mally held in the raised inoperative position shown but after thewrappers have been severed this gripper is released to engage thewrapper strip. From the rolls the wrapper strips pass through the curved0 guides 33 so as to be engaged by the gripper 36, which serves to alinethe wrapper when the cylindrical paper aliner 254 is engaged by theremaining half of the circular perforation 231 in the end of the wrapperstrip. The gripper, after it has moved up and engaged the end of thewrapper strips, may then if desired, definitely aline them by pushingthe wrapper back through the feeding rolls which are then in theirreleased that a greater length of wrapper may be withdrawn. and thegripper, instead of forcing the wrapper back into alinement after firstengaging it, may withdraw a suitable additional length at any time inthe travel of the gripper when the feed rolls are in disengagedposition.

The heavy frame of the machine may be made of suitable side members suchas 83 and 84 connected by suitable rigid braces and this frame may carrythe supporting bracket 85 on which the paper feed plates 10, 15, may bemounted. The driving shaft 48 may be mounted-in the machine frame in anydesired way and may be operated by the pulley 222 or otherwise and maybe turned over for adjustment by the hand wheel 221. This drive shaftmay carry the gear 47 meshing with the idler gear 46 on the shaft 49,which also meshes with the gear 45 on the paper feeding shaft 444 Theshaft 50 also carries a similar idler 51 meshing with the gear 47 andalso meshing with the gear 52 on the cam shaft 55 so that all theseshafts are operated in unison. The sprocket .225 on the paper feed shaft44 operates a suitable sprocket chain 223 which engages the sprocketwheel 224 on the shaft 17 of the cutting roll, see Figs. 2 and 3. Theshaft 18 of the cotiperating feeding roll is driven by the meshing gears228, 229 on these two shafts. The gripper 36 may, as

indicated in Fig. 1, be mounted in a suitable slide 219 in the frame andmay be operated by the link 38 through a stud 37 and pivoted at one endof the gripper lever 40 by a bolt 39 and which, as indicated in Fig. 2,oscillates about its pin 42. This gripper lever carries the cam roll 41meshing with a suitable inclosed cam groove in the cam 43 on the shaft44. The movable gripper jaw 256 is pivoted about the pin 218 shown inFigs. 12 and 13 and is normally swung toward the opposing stationarygripper jaw 36 by a suitable light spring 255. A suitable releaser 172may be used to control the position of the movable gripper jaw and thisreleaser may be slidingly mounted in the guide 173 on the gripper slide219. As long as the releaser is in the osition shown in Fig. 12, itforces the tail 175 of the gri per jaw into such position. as to swing te connected movable gripper jaw 256 away from the cooperating jaw" 36.As the gripper moves upward the releaser-172 engages the adjustablegripping stop 170 on the the feed raiser 73 may operate. as is.indicated in Fig. 2, may be provided slideway 220 and wedges thisreleaser downward into its ide so as to force itout of engagement withthe gripper tail 175, thus allowing the gripper jaws to engage thewrappers. As the gripper. is drawn downward together with the wrappersthe releaser 172 finally comes into engagement with the adjustablereleasing stop 171 so as to wedge the releaser up into engagement withthe gripper tail 175 opening the grip- .per jaws and releasing thewrappers. The

lower ends of the wrappers are thus left resting in the notches 253 ofthe adjustable paper stops 174' shown in detail in Fig. 13.

The cakes of material such as the large cakes of compressed yeast usedby bakers require careful handling and for this reason it is desirableto have a readily controlled feeding device which may be of thefourmotion type indicated in the drawings. The feed bracket 76 may beformed of two outer plates as indicated in Fig. 4, between which Thisraiser with two or more inclined cam portions which coiiperate withsimilarly inclined sta- V tionary raising cams 74 on the bracket. Thefeed raiser is thus vertically raised as it is longitudinallyreciprocated by any desired means, such as by the link 78 engaging thepin 75 on the raiser connected at its other end with the raiser lever 79which is pivoted about the pin 82 as shown in Fig. 1. The follower 80 onthis lever engages the closed cam groove9l in the raising cam 81 on theshaft 55 so as to reciprocate this feed raiser at the proper time andcause a slight vertical movement of the raiser'and the heavy platefeeder 71 supported thereby and guided laterally between the plates 76.This feeder may be reciprocated by a feed rod 61 pivotally or otherwiseremovably. secured to the pin 69 in the bracket 70 on this feeder andhaving its other end loosely hooked over the crank and pin 60 mountedupon the aliner rod 59, as shown in Fig. 2. The operating arm 58 of thiscrank may be connected by the link 57 with a suitable yoke passing overthe shaft 55 and supporting the follower 56 so that it cooperates withthe closed cam groove 54 in the cam 53 so that the raiser is firstraised slightly, carrying the feeder -71 and the cakes 72 clear of thefeed table 257' and then the feeder is moved forward about the width ofa cake before the raiser again lowers, leaving the cakes supported ateither side of the table. It is desirable in feeding such friablematerial to have a safety device on the feeder to prevent over feedingand possible crushing of the articles;

This may be conveniently effected by having a suitable relief connectionin the feed rod 61 by securing the guide 62 on one end of the rod andinterposing a suitable spring 67 between the pin 63 on this guide andthe omo-re pin 68 on the end of the other'section of the feed rod. Thislimits the feeding pressure and a further desirable .safety device mayconsist of the yielding aliner 108 in the path of the cakes as indicatedin Figs.*6'to 8,

This aliner is mounted on the aliner rod 59 supported in suitablebrackets mounted upon the frame 84 and the aliner may be normally heldimproper position by the alining spring 120 which allows the aliner toyield in case of excessive'pressure of the cakes thereon so as tominimize breakage. The stop pin 114 is supported in the bracket 112,113, inthe frame and its head 118 is normally down out of the path ofthe feeder stop"119 on the feeder 71, as shown'in .Fig. 7. If, however,thealiner is tilted by excessivepressure of the cakes the collar 116- iscorrespondingly raised so as to exert through the, spring 115 suflicientpressure on the'stop pinthe end of the feeder by a suitable lifterwhichas" indicated in Figs. 7 and 8 ma comprise the two lifter members 123-oneac side of the feeder 71 and having curved arms 122 to avoidinterference with the aliner rod and supportedon thelifterslide 124guided in the ways 121 asshow'n in ig. 7. This lifter slidesmay' berecipjrocated by the link 136 connected to the pin 137 in the slide andpivoted at its lower-end to the free end of the lifter lever 182 whichis mounted on its pin- 185. ,This'lifter lever carries the follower 1'76coiiperating with a suitable cam groove in the cam 230-01; the

shaft 55 as shown in Figs. 1-a'nd4; It is also desirable to havea-suit'able disengager to'positively disengage the aliner from. theforward cake beforethe lifter'members v123 on each side of the feeder"raise the-cake therefrom.- This may- ;convenien'tly effected byproviding-"the adjustabledi'sem gager -110 on they top of the lifterslide so that it engages the aliner tail 111-s'o as to the first cakebefore itis raised int-o the upper position shown in Fig. 12, where itis engaged and forced forward by the printing plunger. 93 having thehead 95. This printing plunger 93 may be mounted o'n'the slide .andreeiprocated at the proper time by the suitable link 89 connectingthisslide to the u )per mid of the plunger lever 88 as shown in Fig. 1.This plunger lever may be pivoted about the pin82 and carry the follower87 cooperating with a suitable closed cam groove in the cam 86 on theshaft 55 as shown in Fig. 4 so as to force the cake forward, carryingtherewith the .rearplath slide 208 may be mounted in the ollower 212'cooperating with the cam the a-liner out of engagement with. old thisbrush up in the inoperative posi- -front of the p 'rear'. platen '207 onthe slide 208 so as to move gradually back behind the cake in with theprintingplunger to' insure thejproper' .printing action thereof. Thisthe guideway 209 shown in Figs. 1 3 and 1 2 and reciprocated at theproper time by the connecting link 210 and the platen lever 211 ivotedabout the pin 198 and having groove in the cam 213.

It is desirablevwith such soft friable Jmaterial as yeast to insure thepropercleaning of the printing head or die after each im-f pressionandfor this purpose a. suitable- 5::-

cleaning brush maybe mounted to cooper 'ate with the printing plunger asshown in Figs. 6 to 18. This brush 97 may bemounted in the verticallymoving brush frame 98}..-

guided on the pins 99, 103', in the-bracket 100; On the hollowstub-shaft 2660f this brush a suitable brush pinion 102 may be mountedso as to cooperate with the stationary. 'brush rack 101 and rotate thebrush asit is raised and lowered. ,It is also desirable 1 a) change theangular position'of this brush from time to time and this may beconveniently effected by providing a series of angula-rly spaced slots.104 in the hollow brush shaft 266 and havin a pin 267 on- 'therelatively movable br'us stem '268 so that by withdrawing this brushstem against the pressure of the spring 105 by takin hold' of the head265 the pin267 may he s ip (1 into another of these notches. This brus 1automatically raised by the lifter so asto be keptoutof contact with thecakes andthis may be etf ected by providing the lifter pin 107 so as tocoiiperate with the "bracket 96 on -the brush. frame and thus carr the Ibrush; upward as the lifter is raised. hen,' as the printingplun er/93moves forward the guide 94; on the s de of this plunger, as shown inFig. 6, moves forward under thefiuide lug 250 on the brush frameso' asto tic-n shown until the plun er again withdraws, whereu on the brusfalls down in lilnger face so as to clean it, 7 the fall being cushionedby springs such as 106 on the guide rod 99.

-- As the cake72 is forced by the printing plunger between thestationary folding bars and'-126, the wrappers'a're thereby 'fold-811*81011I1d the cake so asito .inclose it on 126 three sides by thetime the cake comes into pdsition above. the folding plunger 139. Thelower side folder 164 on this plunger then moves upward forming thelower side fold and then the plunger moves bodily up- 130 p positionindicated.

of the wrapper around the same.

ward, carrying with it the cakeiand forming the upper side fold as thewrapper engages the rubber grippers 206 on .the discharger. cated inFigs. 10 and 11, is vertically guided from a suitable bracket 138 whichcarries the dovetail guide 163 fitting in the plunger as is shown inFig. 11. The plunger itself is vertically reciprocated by the bar 150carrying the cam roll 154 fitting in the closed cam groove 149 of thecam 147 on the shaft 48. The lower side folder 164 is pivoted on thefolder slide 141 mounted in a suitable guideway 142 in the plunger, seeFigs. 11 and 12, so as to be vertically recip'rocated by the bar 143carryin the cam roll 144 cooperating with the cfosed cam groove 148 inthe cam 145. This side folder is normally pressed inward in line withthe plunger by a suitable spring 167, but the relatively movable cam 166secured to the plunger holds this folder out in the inoperative positionshown in Fig. 12 when it is in its lowered In this way as this folder ismoved upward it enga es the lower lap of thewrappers some littleistanc'e away from the cake so as to more readily fold the wrappersaround it and then when the folder has moved out of engagementwith thecam, as shown in Fig. 13, this folder snaps in into closeengagement'with the cake so as to hold the wrapper tightly against thesame. When this has occurred the folding plunger 139 moves upward,carrying with it the cake and wrappers which are frict-ionally engagedby the pivoted grippers 206 faced with rubber or similar material andhaving their supports 204 pivoted about the pin 205 in the dlschargerarm 203. This additional frictional engagement on the free end of thewrapper folds it .tightly around the-cake so as to take up any slack,which is also assisted by the top platens 179 which finally come intoengagement with the top of the cake. These top plates may be supportedon the-platen rods 180 in suitable guide brackets so that the weight ofthese platens and rods brings them into engagement with the upperportion of the-wrapper soas to holdthe same down firmly against the cakeand assist the positioning At this time the rear end folders 185, 186,are swung around into engagement with the wrapper ends to make the firstend folds therein. These end folders are pivoted in suitable brackets191, 192, supported from the stationary folding bar 126 and the folderscarry at their upper ends the geared folder sectors 187, 188, meshingwith the folder racks 189 on the r-ack slide 190, see Figs. 9 and 15. Asis seen in Fig. 1, this rackslide 190 is secured to the plunger 193which is reciprocated by the link 194 and rack lever 195pivoted aboutthe pin 198. This rack This folding plunger, as is indi lever carriesthe follower 196 engaging a suitableclosed cam groove in the cam 197 onthe shaft 44 as shown in Fig. 3. When these rear end folders haveoperated the bottom end folders 158, 159, are actuated by the support156 and slide 155 and connected roll 153, shown in Fig. 10, ascoiiperating with the groove 152 in the cam 151. This forces thesefolders 158, 159 upward so as to en gage the overlapping wrapper ends atsome distance from the cake and then, after having partly formed thefold the ends 162 of these pivoted folders move out from under thestationary cams 160, 161 on the folding plungers so that the folderssnap down into firm engagement with the cake and set the folds. The topend folders 177, 178, then operate to form the top end folds and closethem down into holding engagement with the folds beneath. These foldersare pivotally mounted in the folder arms 181, 183 on the folder shaft128 and are provided with suitable light springs 184 normally tending tooscillate these folders in toward the cake. As the folders are broughtdown toward the cake and wrapper the pins 251 connected with thesepivoted folders engage the cams 252 so as to rock the lower edges of thefolders out slightly and facilitate starting of the folds. Then, whenthese pins 251 ride past the lower ends of these cams the springs throwthe folders inward against the ends of the cake so as to complete andset the folds. The cam pins 251 on the up.- ward movement of the foldersride against the stationary cam surface 262 and move past the pivotedcams 252 which are normally held in the position indicated in Fig. 16 bythe light springs shown. The folder shaft'128 is oscillated at vtheproper time by the arm-129 shown in Fig. 2, connected thereto andpivoted to the cam rod 130 hav- I ing a guide yoke at its lower end toembrace the drive shaft 48 and hold the cam follower 131 in engagementwith the cam groove 133 in the cam 134 on this shaft. The dischargerplate 204 is then moved forward by the discharger arm 203 shown in Figs.9 and 12 soas to carry the cake for ward between the stationary endfolders to form the final end folds in the wrappers, as is indicated inFig. 15. This discharger arm is reciprocated by the link 202 pivoted tothe discharger lever 201, carrying the cam roll 199 coiiperating withthe cam 200 on the shaft 44, as shown in Figs. 1 and 3. The completelywrapped cake 232 shown in Fig. 17, is thus intermittently fed forwardalong 'the discharge table 216, shown in Fig. 2, be-

tween the side guides 215 which hold the end folds of the wrapper inproper position until the wrapped cakes are taken from this table forpacking.
